Excel spreadsheets using Microsoft ODBC for Oracle, have stopped working when we upgraded for database 12.1 to 12.2. We also upgraded the server OS to RH7. I get ORA-01017. the username and password are correct.
If I use the Oracle in OraXXXHome! driver then they work.
Using MS Excel 2016 (32bit), Oracle runtime client 12.2(32bit) on Windows 10 and Oracle server 12.2 on Red Hat 7.
